Southwest Idaho highway construction report for Sept. 14 - Sept. 21
ADA COUNTY
Interstate 84 East resurfacing
Traffic changes begin near the Eisenman Interchange Sunday evening (Sept. 16) for the I-84 Broadway to Eisenman pavement rehabilitation project. East- and westbound I-84 will be reduced to one lane in each direction at 5 p.m. Sunday between the Gowen and Eisenman interchanges. These lane restrictions will continue until mid-November, when construction stops for winter. In addition, the I-84 westbound on-ramp at Eisenman Road will close Sunday for approximately three weeks for work near the ramp. The I-84 Broadway to Eisenman project will rehabilitate 6.1 miles of interstate between the Broadway Avenue and Eisenman Road interchanges. It begins a series of interstate improvements planned for the Treasure Valley through the GARVEE Transportation Program. The program uses Grant Anticipation Revenue Vehicle (GARVEE) bonds to design and construct needed improvements throughout the state in less time than through traditional funding methods. Western Construction of Boise is the contractor on the $12 million project.
Locust Grove Overpass construction
Work started in December 2006 on a new overpass that will connect Locust Grove Road and offer an extended route over Interstate 84 between Eagle Road and Meridian Road. Currently, Locust Grove Road south of Interstate 84 ends near the interstate. The north side of Locust Grove Road also ends near Interstate 84. The inside lane of the eastbound and westbound sections near the construction site closed in March and will remain closed into October. The closure allows for construction of the center overpass pier and new median barrier. Eastbound traffic normally goes from two lanes to four lanes at the Meridian Interchange. With the closure, eastbound traffic is reduced from two lanes to three lanes at Meridian, then broadens to four lanes after the work zone at Locust Grove. Westbound traffic normally goes from four lanes to two lanes at the Meridian Interchange. With the closure, westbound traffic is reduced to three lanes prior to the work zone at Locust Grove, then to the usual two lanes at Meridian. There is temporary concrete guardrail around the lane closures to protect the work zone, and the speed limit is reduced from 65 miles per hour to 55 miles per hour. The new overpass, scheduled to be finished in the winter of 2007, will consist of two lanes in each direction, sidewalks and bike lanes on both sides of the overpass. Concrete Placing Co. of Boise is the contractor on the $5,845,000 project.
U.S. 20/26 (Chinden Boulevard), Cloverdale Road to Hewlett-Packard widening
Crews are working on the north side of Chinden Boulevard as part of a project to widen the roadway between Cloverdale Road and Hewlett-Packard. Throughout the construction work zone, one lane of traffic on Chinden is maintained in each direction during daytime hours. Periodic nighttime lane closures can be expected between 8 p.m. and 5 a.m. Flaggers will guide motorists through the work zone. Access to businesses and residences will be maintained. Night and weekend traffic is required to use the Cloverdale entrance on the west side of the HP campus. Joplin Road is closed from the Chinden/Cloverdale intersection to Ancell Lane. Motorists can access Joplin at its eastern intersection with Chinden (near Mountain View Drive). Following completion of drainage work and pipe installation, the City of Boise will install underground sewer lines in the same area. After sewer work is complete, the Ada County Highway District plans to resurface Joplin Road. The Chinden project will add bicycle lanes to both sides of the roadway. Curb, gutter and sidewalk will be installed along the south side of the road. By the project's completion, pedestrian and bicycle facilities will extend from Eagle Road to the Joplin Road/Mountain View Drive intersection. In addition, a new half-mile-long frontage road will provide access to homes on the north side of Chinden between the west end of Joplin and HP. As a result, the Chinden/Joplin intersection will be reconfigured. To expedite the project, crews will work an aggressive schedule, including some night and weekend hours. Central Paving Inc. of Boise is the contractor on this $5.5 million project. This is the third phase of work to widen Chinden Boulevard. When completed, Chinden Boulevard will be five lanes from Eagle Road through Garden City. The entire project is expected to be finished in late 2007.

Dunnigan Creek Bridge
Construction started in June to replace the Dunnigan Creek Bridge over Mores Creek. The bridge is located 14 miles south of Idaho City and seven miles north of High Bridge. Dunnigan Creek Bridge will be torn down and replaced with a taller, wider structure. The bridge is at least 70 years old. The new bridge will include new guardrail to improve safety. Slope stabilization also will be done along Idaho 21 before and after the bridge. There will be a temporary crossing over Mores Creek while the new bridge is built. The temporary crossing will maintain one lane in each direction for motorists. The speed limit in the construction area will be reduced to 25 miles per hour from 45 miles per hour, and signs will be posted informing motorists of the speed reduction. There will be occasional traffic stops at approximately 15-minute intervals at the construction site. There may be some construction activity on weekends. The work is scheduled to be finished late this year. McAlvain Excavation is the contractor on the $2.3 million project.

Interstate 84, Exit 29/Franklin Interchange rebuilding
The Exit 29/Franklin Road Interchange is being rebuilt to improve access to Caldwell from I-84, improve traffic flow and ease congestion. The interchange rebuilding project, which started in early December 2006, will enhance several aspects of the interchange. The current two-lane Franklin Overpass will be replaced with a six-lane bridge. The new overpass will have two through lanes in each direction and dual left turn lanes in each direction. The interchange ramps are being lengthened and widened to two lanes at their intersection with Franklin. Work on this part of the project started April 10. Eastbound on-ramp traffic from Franklin Road onto Interstate 84 is using a temporary ramp. Westbound off-ramp traffic from Interstate 84 onto Franklin Road also is using a temporary ramp, just west of the current ramp. Both temporary ramps are a single lane each. Those ramps, scheduled to be in place for several months, will allow crews to rebuild the closed ramps. Once finished, the new ramps will offer two lanes each. The eastbound off-ramp and westbound on-ramp will have traffic shifted to temporary ramps at a later time. The project also involves widening Franklin Road from two to five lanes between the overpass and Specht Avenue. The new road will have a curb, gutter, sidewalk, bicycle lanes and shoulder. Aviation Way will be widened at the intersection with Franklin Road. A new traffic signal also will be added. Lanes may be reduced temporarily on Franklin Road and Aviation Way during the widening. Both roads will remain open during construction. One or both lanes of I-84 may be closed between 7 p.m. and 5 a.m. for safety while crews replace the overpass. Traffic will be detoured. A new bridge and three new lanes will be constructed before the old overpass is torn down and traffic will use the new three lanes while crews replace the old bridge. At the project's completion, all six new lanes will be opened. Traffic updates will be posted to the transportation department's 511 service (511.Idaho.gov, or dial 5-1-1). Concrete Placing Co. is the contractor for the $25 million project. Construction is scheduled to be finished in the fall of 2008.
I-84B Blaine Street/Cleveland Boulevard repaving
A repaving project is under way on Blaine and Cleveland, from 10th Avenue South to just east of South Florida Avenue. The roadway is being rebuilt and paved to the edge of new curb and gutter along both streets. Central Paving Company Inc. is the contractor for the $2.8 million project. During the roadway rebuild, parking and lane restrictions will be necessary. To expedite the project, crews are working an aggressive schedule, which may include some night and weekend work. Completion is scheduled for late 2007. Work was recently completed on a project to replace curb and gutter on Blaine Street and Cleveland Boulevard, from 10th Avenue to 22nd Avenue in Caldwell. The $1.8 million project, once the road surfaces are finished, will improve drainage and eliminate dips at side street intersections. Braun-Jensen Incorporated was the project contractor on the curb and gutter work. Both projects will result in improved sidewalk access. Americans with Disabilities Act-compliant pedestrian ramps will be installed at sidewalk street corners and ramps will be aligned to the center of crosswalks for easier access. Blaine Street and Cleveland Boulevard (Interstate 84 Business Route) are the two major east/west corridors that move traffic through a residential area to a commercial area farther east. These streets also are collectors for side streets and have large numbers of traffic, particularly during rush hours.
I-84B Nampa/Caldwell Boulevard resurfacing
Two miles of Nampa/Caldwell Boulevard (I-84B) between Karcher Road and Northside Boulevard are being repaved. On Sept. 4, construction continued on the westbound lanes. From 8 p.m. to 6 a.m. Sunday through Friday, the westbound lanes will be closed. Between those hours, vehicles will be shifted to the eastbound section, where they will have one lane in each direction. During day-time hours, the right lane of the westbound section will be closed for curb, gutter and sidewalk work. That work will continue until about Sept. 21. The inside westbound lane will be open for vehicle use. Flaggers will direct traffic as needed. The project will improve the road surface for commuters and local traffic entering downtown Nampa. In a partnership with the city of Nampa, the transportation department will add sidewalks, curb and gutter to the north side of the roadway. The city and its local improvement district will cover the cost of the additions. Access to businesses will remain open. The resurfacing is a companion project to the I-84 Karcher Interchange, which opened at the end of the 2006 construction season. The transportation department scheduled the boulevard resurfacing after the interchange project to give commuters another route during peak travel times. The boulevard surface has long outlived its 20-year lifespan and is badly deteriorated. Central Paving Co. of Boise is the contractor for the $5 million project.
Interstate 84, Notus Interchange to Sand Hollow Interchange repaving
Work started May 7 to rebuild a deteriorated section of Interstate 84 between the Sand Hollow and Notus interchanges. It will repair rutting and deterioration, and extend the life of the roadway. Pavement in the project area was originally built with the interstate in the 1960s, and received minor maintenance in 1985 and 1997. In May, equipment was moved into the project area where two crossovers were built to shift interstate traffic and a portion of the detour area was paved. On Aug. 22, traffic was shifted to the Interstate 84 westbound lanes. Those lanes will be one lane in each direction for eastbound and westbound vehicles. The shift is allowing crews to start repaving the eastbound section of Interstate 84 in that area. The westbound Exit 26 (Notus) on-ramp, the westbound Exit 25 (Middleton) on- and off-ramps and the westbound Exit 17 (Sand Hollow) off-ramp will be open. The eastbound Exit 17 on-ramp, the eastbound Exit 25 on- and off-ramps and the eastbound Exit 26 off-ramp are closed. The detour for the ramp traffic is Old Highway 30. The speed limit is reduced to 55 miles per hour through the construction area. Idaho Sand & Gravel is the contractor on the $14 million project, scheduled to be finished in early November.
